Alier, 11, a young cattle herder displaced by fighting in Bor town, stands covered with ash - used as a natural insect repellent - in a cattle camp outside Mingkaman where he, his family, and upwards of 100,000 other displaced civilians now live.

Ferock, 13 sits atop a broken-down car in the Malakal PoC site where he lives. He and his family fled their home last February as fighting between government and opposition forces continued to tear through the area.
